Изобретение относитс к области фармацевтической промышленности и касаетс получени лекарственных веществ из водных экстрактов.This invention relates to the pharmaceutical industry and relates to the preparation of medicinal substances from aqueous extracts.
Известен способ концентрировани водных растворов путем выпаривани в пленочных выпарных аппаратах, заключающийс в нагревании до кипени раствора, испарении с последующим разделением пароводной смеси на специальном устройстве на концентрат и отработанный пар 1.There is a method of concentrating aqueous solutions by evaporation in film evaporators, which consists in heating the solution to boil, evaporating and then separating the steam-water mixture on a special device for concentrate and exhaust steam 1.
Однако известный способ вл етс трудоемким .However, the known method is laborious.
Целью изобретени вл етс упрощение технологии производства. Дл достижени этой цели поверхностный слой водного экстракта нагревают до температуры ниже точки кипени и посто нно пропускают стерильный воздух.The aim of the invention is to simplify the production technology. To achieve this goal, the surface layer of the aqueous extract is heated to a temperature below the boiling point and sterile air is constantly passed through.
Способ осуществл етс следующим образом .The method is carried out as follows.
Пример. 1т водного экстракта плантаглюцида нагревают циркулирующим в паровой рубашке паром до 70°С и в течение 4 ч посто нно вспенивают обработанным бактерицидными лампами воздухом, имеющимExample. 1 t of an aqueous extract of plantaglucid is heated with steam circulating in the steam jacket up to 70 ° С and for 4 hours it is continuously foamed with air treated with germicidal lamps
начальную температуру 26°С. Воздух подают через патрубок в количестве 1200 м в час под давлением 120 мм вод. ст.the initial temperature is 26 ° C. Air is fed through the pipe in the amount of 1200 m per hour under a pressure of 120 mm of water. Art.
После вспенивани поверхностного сло экстракта в течение 4 ч и отвода нагретого до 70°С влажного отработанного воздуха получают 50 кг сконцентрированного вещества.After foaming of the surface layer of the extract for 4 hours and removal of moist exhaust air heated to 70 ° C, 50 kg of the concentrated substance are obtained.
Способ вл етс простым и надежным в осзществлении, так как не требует создани вакуума. Предлагаемый способ позвол ет получить экономический эффект, исчисл емый более 100 тыс. руб. в год.The method is simple and reliable in implementation, since it does not require the creation of a vacuum. The proposed method allows to obtain an economic effect, estimated at more than 100 thousand rubles. in year.
